To ALL wHoM 1T MAY CONGE-RN: Y

Be it known that I, JAooB NACHER, of La Crosse, in the county of La Crosse, and Stateof Wisconsin,v

`have invented a new andimprved Machine for Cutting Meat; vand I do hereby declare that the following is a full, clear, and exact description thereof, which 'will enable those skilled. in the art to make end use the same, i reference being had to` the accompanying drawings formingpart of this specification. -l

This invention relates'itoa new and improved method of cutting and chopping .meat for sausages, 8to.,`. whereby the same is more rapidly and economically done. A

It consists in two o'r more knives bolted to a reciprocating 'cross-head, suid knives moving up and down between cleaners, whereby the meot is prevented from adhering to the knives.'

It consists, also, in two pawls, pivoted to a4 connecting-rod attached to said cross-head, which so engage in the teeth of toothed wheels attached to Aa horizontal shaft, on which said shaft is a geared pinion, which, fitting into aV rack on the under side of the meat-box, gives to said meat-bon an intermittent backward and forward motion under said knives. V

It consists, also, of a vibrating-guard, operated by a lover pivoted to the frame of the machine, one or the shorter end of said lever being hit by a start on the endof said meat-block; Said guard is thrown either over one or the other of said wheels, so as to prevent onoorthe othei` ot" said pawls from `engaging in lthe teeth of said toothed wheels, whereby the direction of Atile motion of saidrneat-block is changed. In theaccompanying Figure 1 is s. left side view of my invention.

Figure 2 is a front view ofthesane.

Figure 3 is n central vcntical sectional view of, the same,` token in the'line :t x, iig. 2.

i The frame A is made of joist, and consists of two sideV pieces, joined together at convenient points, so as tp i form a horizontal frame, supported at the proper height by suitable legs, as shown in the drawing, and may be o f any suitable width and length to receive'the knives I, and admit of the forward and backward movement of the ment-block K upon the same, suitable rails being-laid upon the top of the frame A for that prpose.- The meut-block K is made of wood, an'd'is provided with a. rim entirely around the edge of the same, to prevent the meat from falling from said block while being cut or chopped. The meat-block K may be of any desired length, according to the quantity of meat to be out, and must be a little narrower than the top 'of the frumeA. To the frame A, on each sido ot the sance, near the centre, are rigidly secured by bolts orscrews the uprights B.` Said uprights B are made ofiirou, or other suitable materiel, of sufiicient height to allow 4of' the upward and down# ward movement of thecross-head, and are jointed together at the to'p by a metallic cross-bar, boltodtothe `top of snid uprights, as shown in the drawing.' The uprights Bare' provided with a vertical sloththrough each of the sume, toireccive projectionson the endof the cross-head H, and'guide said cross-head in the movement ofthe same, said slots being of suilicient length to permitithe full movement of the cross-head H.

Upon the inside of the right-hand upright, and near the centre of the same, or at any gonvenient'point in the seme, is bolted by one end a metallic brace, D". Said brace D, extending downwards to. the frame A, isbolted firmly theretd,'the object of the said brace D being to furnish t. support for the inner end of the shaft C, saidbr'nce being provided with suitable hearings or boxes therefor. To the outside of the same upright, )3,1 srmly bolted, atfany convenient point-on the same,another .metallicl brace, D, by onefoot' of the same. Said brace D'is'formed or hent in suche mnneras to project outwards horizontally from the frame A, to allow lSucient lengthto the shaft C, between the brace D and the brace D, vto receive the geared wheel C upon the seme,-as shhwn', saidbrace being secured te the frame A by the other foot of the same, by bolts or screws. The object if the said brace-D is to' dup'port the outer end ofthe shaft C, and is provided with suitable bearings in the 'same for that pnrpose,Vv opposite to and in 'the same straight iine with the bearings in the brace D,`as shown.

The-shaft C is made oi iron, of suicient size for'strength, and rotates in bearingsinthe braces D and D, as above described, extending from the said braces D toand through'the brace' D, and beyond the same, so as .to receive the ily-wheel E.. 4'.lhe {1y-wheel E isa'n ironwheel, ond is keyed to the shaft C in the ordinary way` and is provided with a handle, E, by means of which the machine is operated by the hand.

' Y' Upon the shaft C', and rigidly keyed' thereto in the-ordinary way, is an iron .spur-geared wheel F. Upon the underl side of' the top of the frame A, `and' rotatin'g in suitable boxes thereon, is'a metallic horizontal shaft, G.' Said shaft G extends across the frame and beyond the some, so as to receive upon each end of the same a drank, q. The cranks d areprovided, with crank-pins'in the ordinary way, and so as to receive the lower end of the connecting-rodsa, properly constructed and arranged to receive 'said crank-pins, the length of the crank A a being one half of the length of lthe motion required for the knives I1' Theconnecting-'rods a are of the ordinary form, and are pivoted `to the erossehead H also in the ordinary`way,lthe object ofthe said cranks a and -connectie'g-.rods ol being to changethe rotating motion of Athe shaft G into a reciprocating rectilinear motion cf thecross-head H.

To the shaft G, and at one end thereof, and so as that the teeth of the same will engage with` the teeth of. i lthe wheel F, is keyed ,in-the ordinary way the spur-geared -pinion'G. The wheel and the pinion G ,are to i Aeach other, with respect to their y sise and number of teeth, in the ratioof about two to one,` or in any otherI ratio,tso as to give'the required speed totheshaft G. ,j l

` -The crdss-head H ismade of iron, or other suitable material, and extends across from one of the uprights v l 'te the-other, and is 'provided on each end with aiprojection, which, fitting inthe slot inv each of 'said' upright!`v i B, serves to guide the same in the upward and 'downward movement thereof. To the cross-headH, and so as to project downwards 4under the same, and rigidly secured theretoby nuts upon'the same, are twoarms, secured I also at the lower ends of thesaid arms-to the knives I by rivet! orotherwise Said arms' pass through the cross-head H through'a hole bored to receive the same, and are provided 'with `efsorew-thread, so as to receive a nut, both above and below said cross-head 'H,so as the knives I, s .ttached to said arms, may` be adjusted to any convenient height from the 'block or so as just to touch the sameqat the full extent of the downward movement thereof. The knives I are madeof ste'el, or steel and iron combined, are rectangular inform, of any convenient size, and are firmly riveted to the'. said arms on 'the cro'ss7headH, se as to stand ,across the block K, as shown, and may be of. any convenient number, as two,;;' the lower edge of said knives being made sharp,l so asito eut the meatplaced on the block K. v *Upon one side of the'fram'e A, or upon the left-hand side of the same, as shown, and rotating in' suitable lboxes on the some, and sons to be diriectly above the shaft Gr, isa short metallic shaft, L. Upon one, or upon the left-hand end of the shaft L, and properly keyed thereto, :near one of the bearings of the same, 7are Atwo botchedTA f or toothed metallic whebls, a', the notches in one of said wheels hooking o r curving in one direction, and the' l Y notches in the other of said wheels a curving in the opposite direction. Upon said shaft L, andv keyedjrmly i theretofnear the other hearing of the same, iss, spur-glearedpinion, e, so situatedlahdnrrangcd as that the teeth ofthe same will engage in the teeth of the rack e. i l i Upon the under side, and near the left-hand edge of the block, and extending the whole length of saidblock, is a metallic rack, e, into the teeth of which said rack e, the teeth of the pinion, el mesh, as above described, l and-soos that`by rotntngthc shaft L in either direction, the block K will be drieen in the same direction upon' that-rack If, the rotating motion of the shaft L beingchangod into arectilincar motion of the block K.. v

Through the cross-head H, at one end thereof, so as that-tbe lower endet' the some will he in a vertical' line over the wheels a, and so as to extend downwards, is el metallic rod, 1in. Said" rod m is providedlwith a screw-thread upon the upper port of the same, so as to receive a nut thereon, both above and `below the cross.

head H, by means of which the length of sc id rod m below thecro'ss-head H may be adjusted.

[lo the lower end ofthe rodm are p ivoted two pawl-s n, Said pawls 1 are made of iron, and extenddown t from the end ofthe rod1 m, one on one side of the wheels a, and the other on the other sid-e of the saturadas I 'shown in the drawing, iig. 1. Said pawls, unsre provided ontheside of the s'cnie towards each other with hooks, bending upwards, so as that said hookswill engage with the notches in said wheels a?, when the crosshead H is moving upwards, oneofsaid hooks on one of the pawls n being prevented from engaging in the notches ofthe said wheels by the guard o, hereinaftermore fully described, while the other is left free to engage with-thel notches in one ofthe wheels a. The upward movement of one of the pawls engaging in ythe notches in ono of fthe wheels a, turns the shaft Lin one direction, whilerthe upward'movement of the other of said pawls, engaging in the notches of the other of said wheels, turns the shaft L in the opposite direc-tion ;A neither ofsaid pawls n having any e'ect in the downward moyement of the'ssme', the hooks in the same in that case sliding over tlre notches insaid wheels a, said notches being shaped-for that purpose in the usual way.' The hooks in the patois es engage with the notches in the wheels during o nLya small portion of the upward moveinent of'suid pswls 1;,1 so thatblqck K, which is moved undenthe knives I by the shaft L, connected as`abovs described, moves only a short diston'cef1 when nid-bleek steps until` other upward movement of the cross-head' H; the object of seidl y l a um arrangement being to feed the @neet npon the block K4 under the knives I e linie further et each upward move.V ment ofthe seme, and so as that in the dovrnwerd or cutting movement of the knives, the bleekl K wlLnot-be in motion. i
